PID / VOC Gas Detectors

PhoCheck Tiger Handheld VOC Gas Detector

The Phocheck Tiger represents an improvement on the standard PID technology, both in terms of dynamic range, response time and immunity from the effects of humidity.  The extended range allows for industrial Hygiene, leak detection and hazmat applications.  The short response time and immunity from the affects of humidity resulting from the Fence Electrode design means that humidity correction is not necessary. Feature include:

  •     Patented Fence Electrode Technology
  •     Dynamic Range ppb to 20,000ppm
  •     Fast 2 second response
  •     Easy change mini PID detector, electrode stack and lamps
  •     Batteries certified to be charged in hazardous areas
  •     Field interchangeable Li-ion and alkaline battery packs
  •     Battery life up to 30hrs (rechargeable Li-ion), and 15hrs (alkaline)
  •     Flashing LED and loud 95 dB audible alarm
  •     Intrinsically safe (ATEX, USETLC)
  •     Rugged Design with protective , removable rubber boot
  •     5 Year Instrument Warranty
  •     Standard 10.6eV lamp, optional 9.8eV and 11.7eV lamps
  •     Optional selective detection of Benzene with 9.8eV lamp and Drager tube holder














TVOC - ATEX Certified Fixed VOC Detector

Total VOC Detector for Continuous Volatile Organic Compound MonitoringTVOC is a fixed continuous VOC detector for the detection and measurement of total volatile organic compounds (VOCs). Its photoionisation detection (PID) capabilities utilise advanced patented Fence Electrode technology, a 3 electrode format with increased resistance to humidity and contamination.A robust fixed VOC detector, TVOC has a selectable detection range of 0 – 10 ppm, 0 – 100 ppm or 0 – 1000 ppm and is ideal for use in manufacturing and process industries where VOCs are typically present.With a 4-20 mA analogue output, the TVOC VOC detector can be simply integrated into a DCS control system to provide warnings and enable control of high VOC levels in the working environment.ATEX approvals enable a 3 wire TVOC system to be used in Zone 2 hazardous areas, without safety barriers. ATEX and IECEx approvals allow TVOC to be used in Zone 1 hazardous areas, with safety barriers.The TVOC fixed VOC detector utilises a diffusive sample technique resulting in less contamination issues compared to pumped systems, reducing lamp cleaning and servicing requirements. Simple to install service and calibrate, TVOC requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.The TVOC fixed VOC detector is also available for use with a pumped system for applications where sample conditioning is required.TVOC is part of a range of VOC detectors that includes the hand held PhoCheck Tiger, PhoCheck+ and FirstCheck+ instruments.
